What Is an Asthma Attack?

An asthma attack may include coughing, chest tightness, wheezing, and trouble breathing. The attack happens in your body』s airways, which are the paths that carry air to your lungs. As the air moves through your lungs, the airways become smaller, like the branches of a tree are smaller than the tree trunk. During an asthma attack, the sides of the airways in your lungs swell and the airways shrink. Less air gets in and out of your lungs, and mucous that your body makes clogs up the airways even more.

You can control your asthma by knowing the warning signs of an asthma attack, staying away from things that cause an attack, and following your doctor』s advice. When you control your asthma:

you won』t have symptoms such as wheezing or coughing

you』ll sleep better

you won』t miss work or school

you can take part in all physical activities

什麼是哮喘發作？

哮喘發作可能包括咳嗽、胸悶、氣喘和呼吸困難。哮喘發作發生在氣道，即空氣進入肺部的通道。當空氣進入肺部時，氣道變得狹窄，如同樹榦上的樹枝變窄一樣。哮喘發作期間，肺部兩側氣道腫脹、收縮，僅有少量空氣進入肺部，機體分泌的黏液可能會讓你的肺部阻塞的更快。
